SUPPLY AIR TEMPERATURE SENSOR — A factory-
installed supply air temperature sensor is provided with
PremierLink™ controller for the water source heat pump
equipment. The sensor is a 10k ohm thermistor, which is
installed in and protected by a stainless steel housing probe.
Probe size is
1
/
4
in. diameter by 1.5 in. long. Wire size and type
are 22 AWG (American Wire Gage), 7/30 copper wire, and
PVC white, 2 conductors.
LEAVING WATER TEMPERATURE SENSOR — A factory-
installed leaving water temperature sensor is provided with
PremierLink controller for the water source heat pump equip-
ment. The sensor is a 10k ohm thermistor, which is installed in
and protected by a stainless steel housing probe. Probe size is
1
/
4
in. diameter by 1.5 in. long. Wire size and type are 22 AWG,
7/30 copper wire, and PVC white, 2 conductors.
Field-Supplied Hardware —
The PremierLink control-
ler is configurable with the following field-supplied sensors:
• space temperature sensor (33ZCT55SPT, 33ZCT56SPT, or
33ZCT58SPT) in sensor mode or thermostat mode for
economizer control
• indoor air quality sensor (33ZCSENCO2, 33ZCT55CO2,
33ZCT56CO2) required only for demand control
ventilation
For specific details about sensors, refer to the literature
supplied with the sensor.
SPACE TEMPERATURE (SPT) SENSOR — A field-supplied
Carrier space temperature sensor is required to maintain the
space temperature in sensor mode. There are three sensors avail-
able for this application:
• 33ZCT55SPT, Space Temperature Sensor with Override
Button
• 33ZCT56SPT, Space Temperature Sensor with Override
Button and Set Point Adjustment
• 33ZCT58SPT, Communicating Room Sensor with Override
Button, Set Point Adjustment, and Manual Fan control
INDOOR AIR QUALITY CO
2
SENSOR — An indoor air
quality sensor is required for CO
2
level monitoring. Three
different CO
2
sensors are available for this application:
• 33ZCSENCO2 sensor is an indoor, wall-mounted sensor
with an LED (light-emitting diode) display
• 33ZCT55CO2 sensor is an indoor, wall-mounted sensor
without display. The CO
2
sensor also includes a space tem-
perature sensor with override button
• 33ZCT56CO2 sensor is an indoor, wall-mounted sensor
without display. The CO
2
sensor also includes a space tem-
perature sensor with override button and temperature offset
